This invention relates to a carton ada ted to contain food stuffs orother materia in the form of powder, small particles or granulesV orotherwise of such nature that .they may be poured from an opening in aside or cover of the container.

It is my object to provide a novel carton for. goods of this kind,adapted to facilitate the withdrawal of small quantities of the goodsfrom time to time, as required, the de- .vice being particularly usefulin households as a container for salt, sugar or the like.

More articularly it is. my object to provide suc a carton with aslidable closure I5 for a small opening, constructed from the'paperboard or other foldable sheet material from which the body of the cartonis formed and so arranged that a minimum.

of work is required to seal' the carton and to open it. 4

The invention also includes certain other novel features of constructionwhich will be more fully ointed out in the following specification and)claim. In the drawings, which illustrate the best form of my device atpresent known to me,

Fig. 1 is a plan view of theblank for forming my .improved carton, laidfiat; Fig. 2 is a to plan view of the carton assembled andl ao w1th theoutlet opening closed "Fig. -3 is a plan view of the same with theoutlet open and Fig. 4 is a section taken on the line 4-4 of Fig. 3. v

As shown in Fig. 1, the blank for forming the carton is divided bycrease lines into four side walls 5, 6, 7 and 8, adapted to constitutethe body o f the box. A fiange 9 on the wall 5 is arranged to besecr-'ed by adhesive in overlapping relation to the wall 8. Bottom flaps10 are severally foldable inward at right angles to the walls 5, 6, 7and 8. Along the opposite edge of the blank a similar series of flaps,indicated by the numerals 11, 12, 13 14 and 15 is arranged to close thetop of the carton.

- The iiap 15 is designed to be folded upon the exterior o f the otherflaps when the carton is closed. This Hap is formed with an outletopening 16 and another opening 21,

, 59 adapted to. allow access to a slidable closure,

. when said ila as hereinafter described.Y An opening 17 is die-cut inthe flap 13 in such a position that is folded inward at the top of thecarton t e opening 17 will register with the opening 16. The iiap 14 isfolded inward between the flaps 13 and 15 when the carton is closed, andthis iap 14 has a closure strip 18 cut therefrom in such a position thatit lies across and between the openingsv 16 and 17 when the carton isassembled. The closure strip 18 is joined by a crease line 19 to a tab20 and this tab is only partially severed from the flap 14 in theinitial die-cutting of the blank. Thus, the closure strip 18 is held inplace in the plane of the flap 14 by the tab 20. To a cross hatchedarea22 of the flap 13 and the similarly marked closure 18 and top 20 isapplied an adhesive, repellant substance. The surfaces thus indicatedare preferablyr rinted upon with a suitable ink to which t e adhesivesubsequently applied willl not adhere. V

' To secure the blank in box shape, the several walls 5, 6, 7 and S-arefolded at right angles to each other and the flange 9 is then fastenedupon the wall 8 by a suitable adhesive. The several bottom flaps 10 arenow folded at right anglesto their attached side walls and securedtogether by adhesive in overlapping relation, as indicated in Fig. 4.The box is subsequently filled with the granular or powdered goods' andthen the top aps 11, 12, 13, 14 and 15 are successively folded inwardupon each other in the order named, adhesive eing applied between theseveral iiaps-to secure them together Vand seal the carton. The glue orthe like,`thus applied, does not cause adhesion between the closurestrip 18, tab 20 and abutting surfaces of the flaps 13 and 15.

It will be noted thatwhen the carton has thus been sealed the tab 20 isaccessible through the opening 21 in the outer flap 15. When it isdesired to open the'carton and withdraw the contents, the point of aknife may be readily 'inserted beneath the tab 20 and said tab separatedfrom the iap 14, partial separation having been effected previously inthe die-cutting of the blank. The tab is then extended through theopening 21 by 100 `GIS folding it along the crease line 19. Now theclosure 18 is free to slide in the plane of the flap 14 and to beWithdrawn to uncover the outlet openings 16 and 17 by grasping the tab20. Thus, the closure strip 18 may readily be moved from the closedposition indicated in Fig. 2to the open position indicated in Figs. 3and 4.

The opening 17 has an enlargement 23 extending laterally the full Widthof the closure 18 and longitudinally of said closure to its innerextremity. This enlargement 23 prevents the lodging of the granularcontents in the guide way for the closure 18. Any granular materialwhich passes into path of the closure 18, When the latter is in openposition, is pushed back into the carton through the enlargement 23 bymovement of the closure to closed position.

It will now be understood that the pouring opening and closure areformed in the operation of die-cutting the blank and the adhesiverepcllant is applied to the closure 18 and area 22 in the operation ofprinting the blank. As is Well known, such cartons are commonly given anattractive appearance by printing upon the exterior surfaces. Thus, theblank for my improved carton is produced with a minimum of expense.Further, the operation of folding and securing the blank in box form isperformed with the same facility with my improved carton as with cartonsof the common type Without the pouring and closure features.

Having described my invention what I claim as new and desire to protectby Letters Patent is: l

A carton comprising, a body formed from foldahle sheet material, outer,inner and intermediate flaps secured one upon another, said outer andinner Haps having outlet openings registering one with the other and animperforate closure for said openings formed from said intermediate fiapand slidable in the plane thereof to open and close said openings, saidopening in said inner flap being formed with an enlargement extendingthe full width of said closure to permit ready removal of granularsubstances from the path of said closure.

In testimony whereof I have hereunto signed my name to thisspecification.
